reproduces low frequencies up to 150 Hz; the midrange
driver reproduces the frequencies up to 6.5 kHz. The
crossover used in your SARASTRO II is a mix of 1
st . order
between the woofer and midrange units and 3 rd . order
between the mids and high frequency units.
Just like all Verity Audio loudspeakers, The SARASTRO II
works with the room reinforcement characteristics to
produce quick and solid bass performances. Despite its
small size, the SARASTRO II loudspeaker provides a low
frequency extension down to 20 Hz.
The midrange woofer unit has been optimized for
maximum cone rigidity without breakup resonance. This
special unit is offering a low level of distortion, extended
dynamics range, high-power handling, and simple dividing
network.
The tweeter has been specifically designed to give
extended, natural and resonance free reproduction of the
harmonic content of all musical instruments. These units
have been integrated with a very carefully designed
crossover that allows each driver to deliver its full potential.
Moreover, all components used are carefully computer-
matched and indexed to enable optimum sound staging
performance.
Packing and Unpacking
Before they left the factory, your SARASTRO II cabinets
passed an exhaustive quality control procedure to guaranty
their genuine state. Please observe carefully the following
unpacking instructions for maximum product safety. Once
your SARASTRO II cabinets will be unpacked, inspect them
carefully for any physical damage. If any transit damage
can be noticed, please notify your dealer immediately and
request the carrier’s name so a written claim can be
initiated.
Your SARASTRO II comes packed in a double cardboard
box complete with all the necessary protection accessories.
For transportation purposes, we strongly recommend you
to keep and store all your packaging
hardware.
Unless the carrier is notified promptly and all the shipping
cases are available for inspection, the right to claim can be
forfeited.
Installation
This section depicts how to assemble and connect the
SARASTRO II loudspeaker.
To identify a proper location for the installation of your
SARASTRO IIs, please refer to the Room Placement section
of this manual or follow the recommendations of your
dealer.
Once the speakers are properly installed, connect them to
your amplifier by using quality speaker cables. Make sure
that polarities are respected at both ends and that your
cables are installed in the proper direction. The positive
input is identified by a red dot located on the connector
plate.
For vacuum tube equipment that has multiple output
impedance taps, the four-ohm taps should provide the
best interface with the SARASTRO II.
Room Placement
Indoors, acoustic intelligibility is of great concern for a
variety of reasons. It requires low background noise levels
and “good” acoustical design. In any room, the reverberant
sound pressure level increases as the acoustic power
increases and decreases as sound absorption in the room
increases and / or sound power flows from the room. The
sound field in a room is composed of two parts, the direct
field and the reverberant field.
The complex theories of physical acoustics, the
uncertainties in predicting the property variations of both
natural and manufactured room materials, and the none
negligible effects of painting, sealing, bracing, furring, and
draping all keep the specification and prediction of room
acoustics from being an exact science. Adding together,
loudspeaker characteristics, the auditory personal taste
and ergonomics make, by practical means, the equation
impossible to solve. The frequent need to evaluate the final
result by listening rather than by purely quantitative
methods gives acoustical tuning a somewhat subjective
aspect.
Nevertheless, knowing what the SARASTRO II is capable to
do will be your major asset in establishing the best setup
for your loudspeaker. Here are a few simple rules that will
guide you. A good setup will give you fast transients from
bottom-end to top-end, proper image height and a wide
and deep soundstage.
The following guidelines are based on our own experience
with the SARASTRO II. We recommend you to start with
Over tightening the connectors could cause
permanent damage.
